Farraj, Abdallah (2012-08-22)This dissertation investigates the use of advanced acoustical communication techniques for wireless downhole telemetry systems. Using acoustic waves for downhole telemetry systems is investigated in order to replace the ...
-
Hall, Varrian Durand (2009-05-15)The rapid growth of new wireless and mobile devices accessing the internet has led to an increase in the demand for multimedia streaming services. These home-based wireless connections require efficient distribution of ...
-
Lee, Heung Ki (2011-02-22)Web cluster systems provide cost-effective solutions when scalable and reliable web services are required. However, as the number of servers in web cluster systems increase, web cluster systems incur long and unpredictable ...
-
Rolando, David Lee (2012-02-14)The spherical inverted-F antenna (SIFA) is a relatively new conformal antenna design that consists of a microstrip patch resonator on a spherical ground. The SIFA resembles a planar inverted-F antenna (PIFA) that has ...

Charalambous, Charalambos (2011-02-22)Wireless sensor networks (WSNs) have emerged in strategic applications such as target detection, localization, and tracking in battlefields, where the large-scale na- ture renders centralized control prohibitive. In addition, ...
-
Parthasarathy, Saranya (2012-07-16)This thesis addresses the problem of local intrusion detection for SCADA (Supervisory Control and Data Acquisition) field devices in the smart grid. A methodology is proposed to detect anomalies in the communication patterns ...
-
Panda, Reena (2012-02-14)The increasing gap between processor and main memory speeds has become a serious bottleneck towards further improvement in system performance. Data prefetching techniques have been proposed to hide the performance impact ...
-
Iyer, Bharat Vishwanathan (Texas A&M University, 2005-02-17)Many large-scale random graphs (e.g., the Internet) exhibit complex topology, nonhomogeneous spatial node distribution, and preferential attachment of new nodes. Current topology models for ad-hoc networks mostly consider ...
-
Luh, William (Texas A&M University, 2005-02-17)Digital fingerprinting is a method by which a copyright owner can uniquely embed a buyer-dependent, inconspicuous serial number (representing the fingerprint) into every copy of digital data that is legally sold. The ...
-
Abdelgawad, Marwa (2012-07-16)Homogeneous Charge Compression Ignition (HCCI) Engines hold promises of being the next generation of internal combustion engines due to their ability to produce high thermal efficiencies and low emission levels. HCCI ...
-
Sambasubramanian, Srinath (2011-10-21)Elastography is a non-invasive medical imaging modality that is used as a diagnostic tool for the early detection of several pathological changes in soft tissues. Elastography techniques provide the local strain distributions ...
-
Xiong, Yunli (Texas A&M University, 2005-08-29)In wireless sensor networks (WSN), nodes have very limited power due to hardware constraints. Packet losses and retransmissions resulting from congestion cost precious energy and shorten the lifetime of sensor nodes. This ...
-
Liu, Shan (2013-02-11)The effective modeling and analysis of large-scale power system disturbances especially those stemming from intentional attack represents an open engineering and research problem. Challenges stem from the need to develop ...
-
Deka, Sthiti (2011-10-21)Elastography is a non-invasive imaging modality that uses ultrasound to estimate the elasticity of soft tissues. The resulting images are called 'elastograms'. Elastography techniques are promising as cost-effective tools ...
-
Dwobeng, Ebenezer (2012-02-14)Electrical signals produced in the human body can be used for medical diagnosis and research, treatment of diseases, pilot safety etc. These signals are extracted using an electrode (or transducer) to convert the ion current ...
-
Cybernetic automata: An approach for the realization of economical cognition for multi-robot systems Mathai, Nebu John (2009-05-15)The multi-agent robotics paradigm has attracted much attention due to the variety of pertinent applications that are well-served by the use of a multiplicity of agents (including space robotics, search and rescue, and ...
-
Jainsky, Julien Sebastien 1981- (2012-11-29)Steganography and covert-communications represent a great and real threat today more than ever due to the evolution of modern communications. This doctoral work proposes defenses against such covert-communication techniques ...
-
Dube, Raghav (Texas A&M University, 2005-02-17)The use of Internet has revolutionized the way information is exchanged, changed business paradigms and put mission critical and sensitive systems online. Any dis- ruption of this connectivity and the plethora of services ...
-
Jagielski, Christopher (2012-04-24)This thesis outlines the design of a real-time digital signal processing technique for pitch detection and analysis via spectral analysis. A sound’s musical pitch can be determined from its fundamental frequency, and a ...
-
Luh, William (2009-05-15)This dissertation presents a novel problem inspired by the characteristics of sensor networks. The basic setup through-out the dissertation is that a set of sensor nodes encipher their data without collaboration and without ...
